Most of the fine furniture that exists today is , imho, ridiculously stronger than it needs to be. A typical plywood entertainment center with dadoed shelves and biscuits could hold a TV, all of your equipment, and a minivan, and barely creak. Recognizing that my equipment isn’t all that demanding (ie. I don’t have pets or kids), I decided to focus on cosmetics instead. I don’t like my furniture to be some thing that just sits on the floor—it should all live as matter-of-factly as the floor itself. :-)
The core functionality of an entertainment center is to hold a TV and my components, and hide the wires connecting them. I’ve always hated pulling out components and crawling into a dimly lit crevasse to try to read the wording/coloring on the back of something…so I decided to take a more open approach that would enable my periodic fiddling without the fuss.
So this is what I came up with.
The wood is entirely black walnut. The backbone is secured at 45° to studs in the wall with 2 lag bolts—one hidden behind the TV, the other behind the top shelf. A rabbet runs along its entire top so I can hide wires against the wall. This rabbet is extended by a dado that cuts behind the TV so I can run wires below the backbone without running them all the way over the end.
The shelves are rhombuses, 10° off square, which complement the angle of the backbone as you enter the room. They are supported entirely by a deep dado, which I angled at 2° anticipating some sagging once loaded (I’d probably do 3° or maybe even 4° if I had to do it again). I intentionally committed a woodworking sin and joined the 3 boards making up the shelf with matching grain patterns, specifically u-u-u instead of u-n-u or n-u-n. They will naturally want to warp upwards, which should cancel out with gravity’s insistence on the opposite.
My TV’s mounting pattern was square, which matched my 45° pattern perfectly. I just secured a piece of angle iron to the corners, which sits on top of the backbone. Again, in the spirit of yolo, 4 big bolts is (hopefully) overkill for a 50 lb TV—if I’m wrong, I won’t do it again. I partially screwed in a screw near the bottom, and used a hanger bolt (and nut) near the top, both of which keep the TV from sliding down (or off) the backbone. The angle iron has holes in it already, which make the TV placement somewhat adjustable.
Never seen anything like it, that’s for sure!
